Inherited Liver and Lung Disease

Alpha-1 antitrypsin (AAT) is a protein that is made by your liver and released into your bloodstream where it protects your lungs. Alpha-1 antitrypsin deficiency Lung Disease occurs when your liver does not secrete enough AAT and you are at risk of developing chronic obstructive pulmonary disease (COPD). In addition the collection of the protein in the liver can lead to liver disease and cirrhosis.

Alpha-1 Deficiency is an inherited condition. In most cases severe lung or liver disease does not appear unless both your parents carry the abnormal AAT gene.

Symptoms, Diagnosis and Outlook

α-1缺乏症的症状（AATD）包括：

• Shortness of breath with or without exertion
• Jaundice of the skin and eyes that does not get better
• Unexplained weight loss
• Wheezing
• Dark urine or pale stools

If you have COPD, asthma with fixed lung disease, liver disease or a family history of Alpha-1 deficiency, talk to your doctor about screening for the disease. Early intervention is the key to preventing severe lung and liver disease.

Diagnosis starts with a physical examination to assess whether you have a barrel-shaped chest, wheezing or the decreased breath sounds that accompany Alpha-1 deficiency.

Additional testing may include:

• AAT血液测试
• Liver Function Testing
• Lung function test
• Chest X-ray
• CT scan of your chest
• Genetic testing

With early diagnosis and proper treatment, many people with Alpha-1 deficiency will not develop lung or liver disease. In severe cases, the condition can cause COPD, damage to your airways and liver failure.
